Mobilisation of support for the Palestinian cause : A comparative study of political change at the communal, regional and global levels

Those who study world politics are divided between the traditional Realist paradigm, which depicts an international political system dominated by states involved in a 'power struggle' in pursuit of their 'national interest', and an emergent approach that includes in the analysis a wider range of political actors and defines the nature of politics very differently.The latter approach sees the central process of world politics as being the mobilisation of support in respect to the composition of the global political agenda and contest over the various issue positions. This thesis examines the Palestinian Question as a case study of a mobilisation process, that involved a non-state actor playing a crucial role in introducing to the global agenda an issue previously of low salience to other actors. The Palestinian Question throughout the 1950s and 1960s was treated on the global political agenda as a by-product of the Arab-Israeli conflict. It was perceived as a 'refugee problem', the solution of which was envisaged within an overall settlement of the A.rab-Israeli conflict. Yet, within less than a decade of the re-appearance of an indigenous Palestinian national movement a significant section of the international political system changed its attitude towards the Palestinian problem. It was not any more perceived simply as a 'refugee problem' but one of 'self-determination'. In this thesis the analysis of the mobilisation process that brought the Palestinian issue to the forefront of the world political agenda is guided by a dynamic model applied to four different levels of analysis. The first level is constituted by the Palestinian community. Then there is the Arab governmental level. The third level is made up of various regional groupings, such as the Non-Aligned, the Latin Americans, the European Community and the East Europeans. The final level is the global one, represented by the United Nations political system. The analysis reveals the dynamic and interactive nature of the mobilisation process across different levels of analysis and the way in which the different positions held on the Palestinian issue have converged towards a relatively common stand

Security framework for industrial collaborative robotic cyber-physical systems

The paper introduces a security framework for the application of human-robot collaboration in a futuristic industrial cyber-physical system (CPS) context of industry 4.0. The basic elements and functional requirements of a secure collaborative robotic cyber-physical system are explained and then the cyber-attack modes are discussed in the context of collaborative CPS whereas a defense mechanism strategy is proposed for such a complex system. The cyber-attacks are categorized according to the extent on controllability and the possible effects on the performance and efficiency of such CPS. The paper also describes the severity and categorization of such cyber-attacks and the causal effect on the human worker safety during human-robot collaboration. Attacks in three dimensions of availability, authentication and confidentiality are proposed as the basis of a consolidated mitigation plan. We propose a security framework based on a two-pronged strategy where the impact of this methodology is demonstrated on a teleoperation benchmark (NeCS-Car). The mitigation strategy includes enhanced data security at important interconnected adaptor nodes and development of an intelligent module that employs a concept similar to system health monitoring and reconfiguration

Understanding vulnerabilities in cyber physical production systems

Development of future manufacturing systems is featured with flexibility, mass customization, intelligence and context based learning to produce smart products. These production systems are characterized through networked, cooperating objects called cyber physical systems (CPSs). From the manufacturing perspective, the ability to communicate data and develop interaction between devices, manufacturing machinery, raw materials, working robots, humans and the plant environment develops the concept of cyber physical production systems (CPPS). Human-robot collaboration is a technology area that will be an integrated part of the future factory floor and the CPPS. With the involvement of human part in the automated system industrial scenarios, practical safety issues are expected to arise in the connected environment due to the use of a large number of devices, sensors, and cloud services causing complex network, IP conflicts, compromised nodes and communication issues. This all may lead to occupational safety issues on the factory floor in different ways and combinations. Overall, the system's physical vulnerability will be increased in the context of compromised connected working space and cyber-security. In this paper, the authors developed a risk assessment based on system vulnerability of a CPPS developed for a use case requirement and performed a simulated approach by launching a cyber-attack and measuring the causal effect to identify implications on human worker safety

The Australian Racism, Acceptance, and Cultural-Ethnocentrism Scale (RACES): item response theory findings

BACKGROUND: Racism and associated discrimination are pervasive and persistent challenges with multiple cumulative deleterious effects contributing to inequities in various health outcomes. Globally, research over the past decade has shown consistent associations between racism and negative health concerns. Such research confirms that race endures as one of the strongest predictors of poor health. Due to the lack of validated Australian measures of racist attitudes, RACES (Racism, Acceptance, and Cultural-Ethnocentrism Scale) was developed. METHODS: Here, we examine RACES’ psychometric properties, including the latent structure, utilising Item Response Theory (IRT). Unidimensional and Multidimensional Rating Scale Model (RSM) Rasch analyses were utilised with 296 Victorian primary school students and 182 adolescents and 220 adults from the Australian community. RESULTS: RACES was demonstrated to be a robust 24-item three-dimensional scale of Accepting Attitudes (12 items), Racist Attitudes (8 items), and Ethnocentric Attitudes (4 items). RSM Rasch analyses provide strong support for the instrument as a robust measure of racist attitudes in the Australian context, and for the overall factorial and construct validity of RACES across primary school children, adolescents, and adults. CONCLUSIONS: RACES provides a reliable and valid measure that can be utilised across the lifespan to evaluate attitudes towards all racial, ethnic, cultural, and religious groups. A core function of RACES is to assess the effectiveness of interventions to reduce community levels of racism and in turn inequities in health outcomes within Australia.

Subtyping patients with heroin addiction at treatment entry: factor derived from the Self-Report Symptom Inventory (SCL-90)

<p>Abstract</p> <p>Background</p> <p>Addiction is a relapsing chronic condition in which psychiatric phenomena play a crucial role. Psychopathological symptoms in patients with heroin addiction are generally considered to be part of the drug addict's personality, or else to be related to the presence of psychiatric comorbidity, raising doubts about whether patients with long-term abuse of opioids actually possess specific psychopathological dimensions.</p> <p>Methods</p> <p>Using the Self-Report Symptom Inventory (SCL-90), we studied the psychopathological dimensions of 1,055 patients with heroin addiction (884 males and 171 females) aged between 16 and 59 years at the beginning of treatment, and their relationship to age, sex and duration of dependence.</p> <p>Results</p> <p>A total of 150 (14.2%) patients with heroin addiction showed depressive symptomatology characterised by feelings of worthlessness and being trapped or caught; 257 (24.4%) had somatisation symptoms, 205 (19.4%) interpersonal sensitivity and psychotic symptoms, 235 (22.3%) panic symptomatology, 208 (19.7%) violence and self-aggression. These dimensions were not correlated with sex or duration of dependence. Younger patients with heroin addiction were characterised by higher scores for violence-suicide, sensitivity and panic anxiety symptomatology. Older patients with heroin addiction showed higher scores for somatisation and worthlessness-being trapped symptomatology.</p> <p>Conclusions</p> <p>This study supports the hypothesis that mood, anxiety and impulse-control dysregulation are the core of the clinical phenomenology of addiction and should be incorporated into its nosology.</p

Concurrent alcohol and cocaine dependence impact on physical health among psychiatric patients

The aim of this study was to examine the association between active, concomitant cocaine and alcohol dependence and the prevalence and patterns of comorbid physical disorders in a sample of substance abusing hospitalized psychiatric patients. Three groups of patients (concomitant cocaine and alcohol dependence (AD + CD) (N = 38), alcohol dependence (AD) only (N = 38), and cocaine dependence (CD) only (N = 25)) consecutively admitted to a psychiatric-substance abuse dual diagnosis unit were comparatively examined for the frequency of comorbid physical disorders diagnoses, including viral hepatitis, sexually transmitted diseases, and on liver function tests and electrocardiographic abnormalities. The results indicated that the concomitant alcohol and cocaine dependence group had higher rates of multiple physical disorders and also of multiple hepatitis infections than either the alcohol-only or the cocaine-only groups

A methodology to develop collaborative robotic cyber physical systems for production environments

The paper identifies the need for human robot collaboration for conventional light weight and heavy payload robots in future manufacturing environment. An overview of state of the art for these types of robots shows that there exists no solution for human robot collaboration. Here, we consider cyber physical systems, which are based on human worker participation as an integrated role in addition to its basic components. First, the paper identifies the collaborative schemes and a formal grading system is formulated based on four performance indicators. A detailed sensor catalog is established for one of the collaboration schemes, and performance indices are computed with various sensors. This study reveals an assessment of best and worst possible ranges of performance indices that are useful in the categorization of collaboration levels. To illustrate a possible solution, a hypothetical industrial scenario is discussed in a production environment. Generalizing this approach, a design methodology is developed for such human robot collaborative environments for various industrial scenarios to enable solution implementation
